Clean, properly formatted CSS is easier to read, debug, and maintain. Our CSS Formatter automatically indents your stylesheets with consistent spacing, placing each property on its own line with proper nesting. Minified CSS removes all unnecessary whitespace to reduce file size for production. Paste your CSS into the input area and click "Format" to get properly indented, readable code. Each property goes on its own line, nested rules are properly indented, and the overall structure becomes clear at a glance. If you need to compress your CSS for deployment, click "Minify" to strip all whitespace and comments, reducing file size. This tool handles all standard CSS syntax including nested rules, media queries, keyframes, custom properties (CSS variables), selectors, and at-rules. It preserves comments during formatting and removes them during minification. The formatter works with plain CSS, SCSS-like syntax, and CSS-in-JS template strings. All processing happens in your browser. Your data never leaves your device. For related formatting tools, try our [JSON Formatter](/tools/json-formatter) or [SQL Formatter](/tools/sql-formatter).
FAQ
Does it handle SCSS?
We handle standard CSS syntax including nested rules. For full SCSS/Less support, consider a dedicated preprocessor formatter, but our tool handles most common CSS patterns.
Will minification break my CSS?
No. Our minifier only removes whitespace and comments — it does not alter property values, selectors, or any functional CSS. The result is identical when parsed by a browser.
Does it strip comments?
Formatting preserves comments. Minification removes them to reduce file size. Comments are a significant portion of CSS weight in production.
